SICK

Wherever access or danger areas need to be reliably and cost-effectively protected, SICK safety systems are in demand. State-of-the-art sensor technology, modular design, compact dimensions and a broad range of applications form the basis for safe and efficient manufacturing processes. SICK's comprehensive expertise in the planning, implementation and operation of safety systems has made them number one in this sector.

SICK offers a product portfolio for automated guided vehicle (AGVs) and system applications, including laser scanners that enable AGVs and AGVSs to navigate and determine positions, as well as safety laser scanners designed to protect people and prevent collisions.

With its DFS60S Pro safety encoder and FX3-MOC0 drive monitor, SICK has expanded its portfolio of solutions for the safe monitoring of the drives of mobile machines and, for example, automated guided vehicles (AGVs).

The GMS800 extractive gas analyser can measure more than 60 different gas compounds. The device's modular design includes up to six analysing modules, one gas module, I/O modules and an operating unit.

Sick's MINESIC100 TPS (truck protection system) is a warning system for collision prevention and lane monitoring, designed for all types and sizes of dumpers and suitable for use in open cast mining applications. The largest of these vehicles is over 15 m long, almost 10 m wide and weighs 570 tons when loaded. This corresponds to a weight of around 330 medium-sized vehicles.

Sick has added the S300 Mini, S300 and S3000 product families to the Scanner Plus! range of safety laser scanners. S300 and S300 Mini safety laser scanners feature easy integration due to their compact design with a protective field range of up to 3 m. The S3000 safety laser scanner offers a maximum protective field range of 7 m, said to be a first for a safety certified scanner.

SICK's in-situ gas analysers are suitable for direct installation in devices at the respective measurement site, eg, on the chimney. The analysers measure directly in the process under actual operating conditions. Characterised by their minimal maintenance requirements and short response times, they are available in two different versions.

Sick safety service solutions provide manufacturers, distributors and operating companies with a means of ensuring that their machines and systems are thoroughly assessed and equipped from the point of view of safety throughout the entire life cycle.

The deTec2 Core safety light curtain from Sick has been added to the deTec range. A type 2 device with PL c or SIL1, the deTec2 Core accommodates the changes to product standard IEC 61496-1 and provides safety for the machine and operator.

The IP67 housing in which the C4000 Micro is integrated is a protective housing with a PMMA acrylic pipe and V4A stainless steel end caps. It is compactly constructed so that no inaccessible areas of dirt can form.

Up to six doors on mechanical separating protective equipment can be centrally monitored with the non-contact RE 4000 safety system. The system, consisting of an evaluation unit with sensors and actuators, is certified as category 4 according to EN 954-1. Thus, the system can be used in potentially highly hazardous machines.

The IN 300 and IN 3000 series are inductive systems whose optional cubic or cylindrical sensors detect the presence of metal. Integration of the manual restart and external device monitoring functions in the evaluation modules of the IN series bring about considerable savings in safety relays, as three (IN 300) or six (IN 3000) sensors can be connected to each module.

The category 4 C4000 micro safety curtain is now available in an IP67 housing. Thus non-contact area safeguarding requiring the highest possible safety category complying with IEC 61496 can also be realised wherever process conditions may involve temperature fluctuations, or cleaning with steam or aggressive detergents.

Industrial operators are faced with a challenging task — to create flexible production workflows with a high level of automation, while at the same time ensuring that their people, machines and plants stay protected.

Modern sensor technologies present new opportunities to detect a hazard before an accident occurs. Road and traffic authorities are now able to mitigate risks of oversized vehicles, overheating brakes, speed, driving conditions and traffic density. Anti-collision safety laser scanners are now used in the warehouse for forklifts in narrow aisles and on the docks for safe container-terminal operations.

SICK has developed the S3000 Anti Collision safety laser scanner for mobile applications which allows two or more industrial trucks to be used in one narrow aisle for the first time due to a sensing range of up to 15 m.

Outdoor industrial environments are constantly changing and to ensure that changes are always detected, SICK has designed its Visionary-B sensors with two eyes, in the form of horizontally offset lenses.

In this article, SICK looks at the possibilities of today's sensor intelligence in industrial 4.0 environments, and their value in improving the safety of people working with machinery in the supply chain.

Plenty of people underestimate the danger of a fire spreading through a tunnel. Smoke and heat have no way to escape, and they spread at rapid speeds. The short amount of time needed for hot axles or cracked brake rotors on trucks or motor coaches to cause a fire is also well established. Despite all this, there is a way to identify overheating parts on a vehicle before it enters a tunnel and to pull that vehicle out of traffic: using the VHD Pro vehicle hot spot detector from SICK.

Container terminals operate on a 24/7 basis, so the demand on availability is extremely high. Collisions involving the boom of ship-to-shore cranes and the ships themselves pose the greatest risk in daily operations.

Sick has been working with tyre manufacturer Continental to improve safety on its tyre-curing presses, which are in use at 16 locations around the world. Continental was seeking to equip the presses with a uniform, global safety concept while achieving optimum ergonomics and flexibility.

The increase in mine productivity has led to a proportional increase in the size of the equipment used. Most vehicles have considerable operator blind spots, due to scale alone. Despite the best efforts of operators, accidents on mine sites remain an industry-wide problem. The reasons for accidents are diverse, so too are the collision scenarios.

In the early days of the industrial revolution, labour was cheap and there was little regard for pain and suffering of injured workers. In more recent times, we have evolved through changes in social attitudes, placing more value on people who work with machines. These changes ensure that we continue to develop safeguarding measures for existing and new machinery. The challenge is to continue to improve the existing safety of machinery and also, as we make advances in technology, any new hazards need to be managed in a way that aligns with what is expected from the modern-day employer.
